Chinese American Immigrant Breast Cancer Survivors And Their Experiences With Post-Treatment Care, Tara Eaton Phd, Kristin Bright Phd, Xin Zeng Mph, Hayley S. Thompson Phd

Journal of Health Disparities Research and Practice

This study examined the experiences of Chinese American immigrant breast cancer survivors with post-treatment breast cancer care and surveillance in New York City. As part of a mixed methods approach, in-depth interviews were conducted with 11 Chinese American immigrant breast cancer survivors treated in a public hospital setting regarding their final breast cancer treatment visit, perceived risk of breast cancer recurrence, and experiences with social and family networks following the completion of treatment. Several salient and shared themes emerged from the interviews including two areas of particular concern regarding the transition from the treatment to post-treatment setting: survivors’ lack of ...


Metastasis-Associated Protein 1 Is An Upstream Regulator Of Dnmt3a And Stimulator Of Insulin-Growth Factor Binding Protein-3 In Breast Cancer., S Deivendran, Hezlin Marzook, T R Santhoshkumar, Rakesh Kumar, M Radhakrishna Pillai 2017 George Washington University

Biochemistry and Molecular Medicine Faculty Publications

Despite a recognized role of DNA methyltransferase 3a (DNMT3a) in human cancer, the nature of its upstream regulator(s) and relationship with the master chromatin remodeling factor MTA1, continues to be poorly understood. Here, we found an inverse relationship between the levels of MTA1 and DNMT3a in human cancer and that high levels of MTA1 in combination of low DNMT3a status correlates well with poor survival of breast cancer patients. We discovered that MTA1 represses DNMT3a expression via HDAC1/YY1 transcription factor complex. Because IGFBP3 is an established target of DNMT3a, we investigated the effect of MTA1 upon IGFBP3 expression ...


Mutations In Braf Are Associated With Higher Levels Of Immune Infiltrates In Microsatellite-Stable Colon Cancer, Jake Rubin, Eduard Porta Parto 2017 George Washington University

Mutations In Braf Are Associated With Higher Levels Of Immune Infiltrates In Microsatellite-Stable Colon Cancer, Jake Rubin, Eduard Porta Parto

GW Research Days 2016 - Present

While BRAF is among the most well-established oncogenes in human cancers, more recently it has garnered attention for its role in suppressing antitumor immunity, especially in melanoma. Because tumor-infiltrating lymphocyte (TIL) density is strongly prognostic in colorectal cancer (CRC)7, we decided to investigate the connection between TIL density and the BRAF-activating V600E mutation in CRC.

We used ESTIMATE to quantify immune infiltrate in samples from the TCGA colon adenocarcinoma (COAD) dataset (n = 216). This is an algorithm that uses the gene-expression signature of 141 immune-related genes to infer the presence of immune cells in the tumor infiltrate. COAD samples ...


Direct Measurement Of Supra-Physiological Levels Of Ascorbate In Plasma Using A Nanophotometer, Bailey Wetherell 2017 University of Northern Iowa

Direct Measurement Of Supra-Physiological Levels Of Ascorbate In Plasma Using A Nanophotometer, Bailey Wetherell

Research in the Capitol

High dose intravenously administered vitamin C (ascorbate) is currently being tested in clinical trials as an adjuvant to current standard of care therapies in a variety of cancers. Intravenous infusion is used with a goal to achieve supraphysiological ascorbate concentrations in blood of at least 20 mM, 300 to 500 times normal healthy concentrations (0.04-0.08 mM). These trials need quick and easy access to information on the levels of ascorbate achieved in the blood to make clinical decisions. Previous methods that quantify ascorbate levels in blood require extensive preparation, time, and materials that may not always be present ...


Fatty Acid Biomarker Detection For Breast Cancer Using Differential Mobility Spectrometry With Non-Radioactive Ion Source, James Joseph Alberti 2017 University of South Florida

Fatty Acid Biomarker Detection For Breast Cancer Using Differential Mobility Spectrometry With Non-Radioactive Ion Source, James Joseph Alberti

Graduate Theses and Dissertations

Differential Mobility Spectrometry (DMS) using a non-radioactive ion source (NRIS) is investigated as a possible medical diagnostic instrument for near real-time detection of breast cancer biomarkers. In previous clinical studies, concentrations of Linoleic, Palmitic and Stearic fatty acids have been observed at different levels in women with carcinoma breast cancer versus women with benign tumors or healthy women showing no signs of breast cancer. Present diagnostic methods require a biopsy of the suspect tissue and a microscopic lab analysis performed to determine its disease state. This process can take hours or days before the patient and doctor are informed of ...

BACKGROUND: Median age at diagnosis of patients with chronic lymphocytic leukemia (CLL) is > 70 years. However, the majority of clinical trials do not reflect the demographics of CLL patients treated in the community. We examined treatment patterns, outcomes, and disease-related mortality in patients ≥ 75 years with CLL (E-CLL) in a real-world setting.

METHODS: The Connect® CLL registry is a multicenter, prospective observational cohort study, which enrolled 1494 adult patients between 2010-2014, at 199 US sites. Patients with CLL were enrolled within 2 months of initiating first line of therapy (LOT1) or a subsequent LOT (LOT ≥ 2). Kaplan-Meier methods were used ...

Zoledronic Acid Alters Hematopoiesis And Generates Breast Tumor-Suppressive Bone Marrow Cells., Jessalyn M. Ubellacker, Marie-Therese Haider, Molly J. DeCristo, Gloria Allocca, Nicola J. Brown, Daniel P. Silver, Ingunn Holen, Sandra S. McAllister 2017 Harvard Medical School

Zoledronic Acid Alters Hematopoiesis And Generates Breast Tumor-Suppressive Bone Marrow Cells., Jessalyn M. Ubellacker, Marie-Therese Haider, Molly J. Decristo, Gloria Allocca, Nicola J. Brown, Daniel P. Silver, Ingunn Holen, Sandra S. Mcallister

Department of Medical Oncology Faculty Papers

BACKGROUND: The bone-targeting agent zoledronic acid (ZOL) increases breast cancer survival in subsets of patients, but the underlying reasons for this protective effect are unknown. ZOL modulates the activity of osteoclasts and osteoblasts, which form hematopoietic stem cell niches, and therefore may affect hematopoietic cells that play a role in breast cancer progression.

METHOD: Immunocompetent and immunocompromised strains of mice commonly used for breast cancer research were injected with a single, clinically relevant dose of ZOL (100 μg/kg) or vehicle control. The effects of ZOL on the bone marrow microenvironment (bone volume, bone cell number/activity, extracellular matrix composition ...


6-Year Experience Of Outpatient Total And Completion Thyroidectomy, Ethan Frank, Joshua Park MD, Alfred Simental, Christopher Vuong MD, Steve Lee MD, PhD, Pedro Andrade Filho MD, Daniel Kwon MD, Yuan Liu MD 2017 Loma Linda University

6-Year Experience Of Outpatient Total And Completion Thyroidectomy, Ethan Frank, Joshua Park Md, Alfred Simental, Christopher Vuong Md, Steve Lee Md, Phd, Pedro Andrade Filho Md, Daniel Kwon Md, Yuan Liu Md

Loma Linda University Student Journal

Outpatient thyroidectomy has become slowly accepted with various published reports predominantly examining partial or subtotal thyroidectomy. Concerns regarding the safety of outpatient total and completion thyroidectomy remain, especially in regards to vocal fold paralysis, hypocalcemia, and catastrophic hematoma. We aimed to evaluate the safety of outpatient thyroid surgery in a large cohort. We conducted a retrospective review comparing outcomes in those who underwent outpatient (n=251) versus inpatient (n= 291) completion or total thyroidectomy between February 2009 and February 2015. Outpatient completion and total thyroidectomy had lower rates of temporary hypocalcemia (6% vs. 24.4%; p< 0.001) and no significant difference in rates of return to emergency department (1.2% vs. 1.4%), hematoma formation (0.8% vs. 0.7%), temporary (2% vs. 4.1%) or permanent (0.4% vs. 0.7%) vocal fold paralysis, or permanent hypocalcemia (0.4% vs. 0%) compared to the inpatient group. Outpatients requiring calcium replacement had shorter duration of postoperative calcium supplementation (44.4±59.3 days vs. 63.3 ±94.4 days; p < 0.001). Our data demonstrates similar safety in outpatient and inpatient total and completion thyroidectomy.

A small, but unique subgroup of retinoblastoma has been identified with no detectable mutation in the retinoblastoma gene (RB1) and with high levels of MYCN gene amplification. This manuscript investigated alternate pathways of inactivating pRb, the encoded protein in these tumors. We analyzed the mutation status of the RB1 gene and MYCN copy number in a series of 245 unilateral retinoblastomas, and the phosphorylation status of pRb in a subset of five tumors using immunohistochemistry. There were 203 tumors with two mutations in RB1 (RB1(-/-) , 83%), 29 with one (RB1(+/-) , 12%) and 13 with no detectable mutations (RB1(+/+) , 5%). Eighteen ...


Principles Of Radiation Oncology, Richard S. Pieters, Linda Ding, Harry Bushe, Jesse N. Aronowitz 2017 University of Massachusetts Medical School

Principles Of Radiation Oncology, Richard S. Pieters, Linda Ding, Harry Bushe, Jesse N. Aronowitz

Cancer Concepts: A Guidebook for the Non-Oncologist

This chapter in Cancer Concepts: a Guidebook for the Non-Oncologist describes the principles of Radiation Oncology. Radiation Oncology utilizes ionizing radiation to treat cancer (and occasionally a few benign conditions). Radiotherapy or radiation therapy (RT) was initially developed in conjunction with diagnostic radiology, but has evolved into a separate specialty. Currently, more than fifty percent of cancer patients undergo RT at some point during the course of their cancer. Most receive treatment with curative intent (radical therapy); however, patients with incurable disease receive shorter, gentler courses of therapy to relieve cancer-induced symptoms.

Using A Conformal Water Bolus To Adjust Heating Patterns Of Microwave Waveguide Applicators, Paul R. Stauffer, Dario B. Rodrigues, Randolph Sinahon, Lyndsey Sbarro, Valeria Beckhoff, Mark Hurwitz

Department of Radiation Oncology Faculty Papers

Background: Hyperthermia, i.e., raising tissue temperature to 40-45°C for 60 min, has been demonstrated to increase the effectiveness of radiation and chemotherapy for cancer. Although multi-element conformal heat applicators are under development to provide more adjustable heating of contoured anatomy, to date the most often used applicator to heat superficial disease is the simple microwave waveguide. With only a single power input, the operator must be resourceful to adjust heat treatment to accommodate variable size and shape tumors spreading across contoured anatomy. Methods: We used multiphysics simulation software that couples electromagnetic, thermal and fluid dynamics physics to simulate ...

Library Articles and Research

Synovial sarcoma (SS) is an aggressive soft tissue sarcoma (STS) that typically occurs in the extremities near a joint. Metastatic disease is common and usually occurs in the lungs and lymph nodes. Surgical management is the mainstay of treatment with chemotherapy and radiation typically used as adjuvant treatment. Although chemotherapy has a positive impact on survival, the prognosis is poor if metastatic disease occurs. The biology of sarcoma invasion and metastasis remain poorly understood. Chromosomal translocation with fusion of the SYT and SSX genes has been described and is currently used as a diagnostic marker, although the full impact of ...

In this report, we systematically examined the role of telomerase activity in lung and ovarian cancer stem cell (CSC) propagation. For this purpose, we indirectly gauged telomerase activity, by linking the hTERT-promoter to eGFP. Using lung (A549) and ovarian (SKOV3) cancer cells, transduced with the hTERT-GFP reporter, we then employed GFP-expression levels to fractionate these cell lines into GFP-high and GFP-low populations. We functionally compared the phenotype of these GFP-high and GFP-low populations. More specifically, we now show that the cancer cells with higher telomerase activity (GFP-high) are more energetically activated, with increased mitochondrial mass and function, as well as ...

Background: Whether a delay in the initiation of chemotherapy for advanced non-small cell lung cancer (NSCLC) can affect overall survival is not well studied. We aim to evaluate the effect of the time interval between diagnosis and initiation of chemotherapy on overall survival in patients with stage IV NSCLC.

Methods: A retrospective review of newly diagnosed stage IV NSCLC patients who received chemotherapy between 1995 and 2012 was conducted. Demographics, histology and site(s) of metastases of patients were reviewed. Time interval between the date of diagnosis and the date of starting chemotherapy was calculated in days. Patients were divided ...
